Note that I am firmly in the camp of wishing for linear transponders on any
bird that we manage to fly. The accomplishments of PE1RAH prove that even a
tiny cubesat can physically support a linear transponder, not just an FM
single-channel transponder. (See
http://www.scribd.com/doc/59006469/le005-r2 ) And I am firmly in the camp
of wishing for HEO satellites if we can ever manage to get one launched
again. Too bad that Bill Gates (or someone with almost as much money as
him) isn't a ham interested in satellite communication.
Just want to set the record straight about the utility of the higher bands.

Hi, W0JT
I agree with you particularly if a radio ham is able to build and not only
to buy his own microwave equipments and antennas in order to experiment
into the X band K band and higher bands and this is why a HEO satellite
with microwave linear transponders is ideal for the serious experimenter
ham.
To bad that I was not able to use my 10450-10452 MHz homebrewed
downconverter and 60 cm dish on the X band transponder of AO40 because
it never was activated because of the onboard explosion and fault of it.
I hope that some day in the future I can use my above X band set up if
the AMSAT-DL will be able to signe a launch contract for P3E because
actually the above setup been not working into the tropo DX frequency
segment is good only for me to receive the Sun-Noise time to time.
